Lynn Basa of Logan Square said she will create a colorful mosaic that will "evoke flowers" at the Argyle stop in Uptown.

"I basically just followed my own aesthetic," said Basa, an abstract painter who teaches at the School of the Art Institute of Chicago. "I felt like the CTA has been going in a fairly sophisticated way in the art that it's choosing."

For the Berwyn stop in Edgewater, West Town sculptor Dorothy Hughes said she plans to create a ceramic piece that will be 8 feet wide and 5 feet tall and a "reflection of natural things in the environment."

"It's like a wand moving through the landscape bringing high and low together," Hughes said. She said she hasn't visited the Berwyn stop but has seen pictures of the wall where her art will go.

Other artists selected: Thomas Denlinger for the Jarvis stop in Rogers Park; Harold Mendez for the Morse stop in Rogers Park; Jim Bachor for the Thorndale stop in Edgewater; Shin Gray Studio for the Granville stop in Edgewater; and Deedee Morrison for the Lawrence stop in Uptown.

What can you really say about Sir Paul McCartney, the former Beatle, pop music pioneer, worldwide cultural icon, and all-around great guy, that hasn't already been said? I mean, seriously. With the Beatles changing music for the better, becoming a pop culture institution and being "more popular...
